San Antonio police still are trying to piece together what happened from two separate but likely related incidents.

At a little after 3 a.m. CT Monday, officers say they received a call from a woman who had knocked on a stranger's door asking for help. The woman, who had a lot of blood on her shirt, told officers she had fought off a sexual assault by biting her attacker's tongue and directed officers to a car where the incident occurred.

Her name was not released because she may have been the victim of a sexual assault

While officers were investigating, a man showed up at a local hospital without a piece of his tongue. Police officials say they received a call from the hospital where the man, whose name also has not been released, had requested doctors reattach another part of his tongue.

He had not been arrested as of midday Monday, and San Antonio Police Department officials were unavailable Monday night to update the case.

The woman was taken by ambulance to a hospital where she was examined for injuries.
